1 1 1 35 Specification of Letters Patent.

all whom may concern:

t known that if, hilanrrn' SonnNsnN, a i i of" the United States, andresident o tne citv of Seattle. coun King, and Wash -gtoin ha e inventedcertain nd useful improvements in Detachable utt. ns, of which thefollowing is a speciention relates to improvements nd more particularlyto buttons his character wherein two parts e adapted to be locked togeher from opposits sides of a garment, to secure the button position foruse.

is the principal object Of the invention to prov e a button having ahead portion provided with openings for receiving the lock g heads of apair of prongs extended locking shoe, or disk, after the said have beenprojected through a garthe like, in such manner as to secure head infunctional position. It is also an object of the invention to provide abutton of this character wherein the head is eouipped with an openingwhich l permit insertion of a tool to release wi l c the locking memberand the disconnection of the,

In accomplishing these and other objects the invention, l have providedthe imdetails of structure. the preferred s or which are illustrated inthe acco1n- ...fVl11Q drawings, wherein re 1 is an enlarged perspectiveview of the two parts of a button embodying the present invention, shownin detached relation.

is a transverse, sectional view of when attached. x is inner face viewof the button head; particularly illustrating the opening and arcuateslot wherein the locking prongs ant heads are inserted.

Referring more in detail to the drawings: 1 designates the head of abutton embodying the present invention comprising an outer circular wall2 provided with a central opening 3, and an inner wall 4 of smallerdiameter than the outer wall and spaced therefrom by a connecting wallor neck 5, which, with the outer wall 1, forms a peripheral flange 6 forentering the button hole of the article with which the button is used.

Adapted to be detachably secured to the head, is a locking disk, or shoe7, of about the same diameter as the wall 4, or larger if Patented Feb,8, 1%21. 192:). serial No. 362,613.

t esired, and provided with two spaced apart prongs, or pins, 9, thatextend perpendicularly therefrom and which, at their outer ends, areequipped with pointed heads 10, having inwardly facing shoulders 11 attheir outer sides facing toward the disk.

To look the par s together, the two prongs are projected, throughopenings 12and13 in the inner wall of the head 1; the opening 12 beingonly of sullicient size to receive the head of the prong extendedtherein, while the opening 13 has an arcuate slot 1 1 leadtherefrom,with the opening 12 as a center, into which the other prong may move,and in doing locking relation with the button head 1.

A spring wire 16 is secured atone end within the button head with itsfree end extended across the slot 14. The wire is yieldable in onedirection to permit it to be pressed from the path of the head when theparts are being locked together but will not yield in the otherdirection and thus will retain the parts in locked position.

In using the button, the locking disk is placed on the inside of thegarment and the prongs 9 pressed outwardly therethrough to expose theheads 10 at the outer side. The button head is then applied to theprongs by inserting one prong into the opening 12 and the other into theenlargeo end 13 of the slot 14 and then turning the head so'that thelatter prong will move along the slot 14: toward its closed end and willpass back of the spring wire 16. W hen the prongs are in this lockedposition the shoulders 11 will each engage the under sides of the wall4: and will prevent the parts from being dctached.

If it is desired to detach the parts, a pointed tool may be insertedthrough the opening 3 in the outer wall of the head 1 and the springwire 16 pressed aside to permit the prong to move along the slot to theopening 13 which will permit unseating of the shoulders and thedisconnection of the parts.

l Vhat I claim as new is:

1. A button of the character described comprising, a head portion havingtwo spaced openings therein and having an arcuate slot leading from oneof said openings about the other as a center, a locking shoe having apair of prongs extending from one side thereor adapted to project intosaid head openings and having locking heads at so will shift the heads10 into their ends which look within the head when the shoe is'turned tomove one ofsaid prongs into the arcuate slot and yieldable means securedWithin the head for retaining the prongs in locked relation to the head.7

2. A button or" the character described comprising a head portion havingtwo spaced openings therein and having an area 3. A button of thecharacter described inner wall having two spaced openings" therein withan arcuate slot leading from one opening about the other as a center, alocking" shoe having a pair of prongs e1;- ten'ding therefrom to beprojected into said inner wall. openings and having shouldered heads attheir ends, for locking the parts together when the shoe is turned onthe head to move one of sa' d prongs into the arcuate slot, and a springwire secured within the head having a free end extending yieldahlyacross the slot to normally prevent removal of the prong from the slotbut which may be pressed aside by the insertion of a pointed toolthrough the opening of the oute wall to permit disconnection'ot theparts.
